Php 获取数据库表名作为列名

这里我试图从四个表中获取数据。我成功地得到了结果。但是，我需要得到过滤结果的表名。例如，我得到了10个结果。3个结果来自TBL_汽车，3个结果来自TBL_自行车，2个结果来自TBL_卡车，2个结果来自TBL_巴士。我想对这些结果应用不同的url链接

如何将数据库表名作为列名来应用不同的url链接到这些结果

$sql = "(SELECT model_name, maker_url, model_url FROM ".TBL_CAR_ADD_MODELS." WHERE model_status = '1' AND model_url != '".$model_url."' AND model_name LIKE '%$q%' LIMIT 3)
    UNION
    (SELECT model_name, maker_url, model_url FROM ".TBL_BIKE_MODELS." WHERE model_status = '1' AND model_url != '".$model_url."' AND model_name LIKE '%$q%' LIMIT 3)
    UNION
    (SELECT model_name, maker_url, model_url FROM ".TBL_TRUCK_MODELS." WHERE model_status = '1' AND model_url != '".$model_url."' AND model_name LIKE '%$q%' LIMIT 3)
    UNION
    (SELECT model_name, maker_url, model_url FROM ".TBL_BUS_MODELS." WHERE model_status = '1' AND model_url != '".$model_url."' AND model_name LIKE '%$q%' LIMIT 3)";
    $res = mysql_query($sql, $CN);
    $rows = array();
    while($row = mysql_fetch_array($res))
    {   
        if(resutls FROM TBL_CAR)
        {
        $rows[] = array('url' => asort_get_url(CAR_HOMEPAGE, $row['maker_url'], $row['model_url']), 'label' => $row['model_name'], 'image' => fa_model_image_path("thumb", $row['maker_url'],$row['model_url']));
        }
        elseif(results FROM TBL_BIKE)
        {
            $rows[] = array('url' => asort_get_url(BIKE_HOMEPAGE, $row['maker_url'], $row['model_url']), 'label' => $row['model_name'], 'image' => fa_bike_model_image_path("thumb", $row['maker_url'],$row['model_url']));
        }
        elseif(results FROM TBL_TRUCK)
        {
            $rows[] = array('url' => asort_get_url(TRUCK_HOMEPAGE, $row['maker_url'], $row['model_url']), 'label' => $row['model_name'], 'image' => fa_truck_model_image_path("thumb", $row['maker_url'],$row['model_url']));
        }
        elseif(resutls FROM TBL_BUS)
        {
            $rows[] = array('url' => asort_get_url(BUS_HOMEPAGE, $row['maker_url'], $row['model_url']), 'label' => $row['model_name'], 'image' => fa_bus_model_image_path("thumb", $row['maker_url'],$row['model_url']));
        }
    }
    echo stripslashes(json_encode($rows,JSON_PRETTY_PRINT));

一种简单的方法是将表名作为常量添加到查询中，例如：

SELECT 'TBL_CAR_ADD_MODELS' table_name, model_name, maker_url, model_url FROM ".TBL_CAR_ADD_MODELS." WHERE model_status = '1' AND       model_url != '".$model_url."' AND model_name LIKE '%$q%' LIMIT 3)
UNION
(SELECT 'TBL_BIKE_MODELS',model_name, maker_url, model_url FROM ".TBL_BIKE_MODELS." WHERE model_status = '1' AND model_url != '".$model_url."' AND model_name LIKE '%$q%' LIMIT 3)
UNION
(SELECT 'TBL_TRUCK_MODELS', model_name, maker_url, model_url FROM ".TBL_TRUCK_MODELS." WHERE model_status = '1' AND model_url != '".$model_url."' AND model_name LIKE '%$q%' LIMIT 3)
UNION
(SELECT 'TBL_BUS_MODELS', model_name, maker_url, model_url FROM ".TBL_BUS_MODELS." WHERE model_status = '1' AND model_url != '".$model_url."' AND model_name LIKE '%$q%' LIMIT 3)

这样，您只需检查table_name列以确定它来自哪个表。

只需将列名用作静态列值

( SELECT model_name, maker_url, model_url, ".TBL_CAR_ADD_MODELS." AS table_name 
  FROM ".TBL_CAR_ADD_MODELS." WHERE model_status = '1' .....
...
if ( $rows[3] eq TBL_CAR_ADD_MODELS ) { ... }
...

另一种方法可能是研究在数据库中创建数据库，可能类似于：

CREATE VIEW ITEM_MODELS AS
    SELECT *, 'cars' as tbl_name TBL_CARS
    UNION
    SELECT *, 'bikes' as tbl_name TBL_BIKE
    UNION
    SELECT *, 'trucks' as tbl_name TBL_TRUCK
    UNION
    SELECT *, 'buses'  as TBL_BUS;

$sql = "SELECT model_name, maker_url, model_url, tbl_name FROM ITEM_MODELS  WHERE model_status = '1' AND model_url != '${model_url}' AND model_name LIKE '%${q}%' LIMIT 3)";
    while($row = mysql_fetch_array($res))
    {   
        switch($row['tbl_name']) {
            case TBL_CAR_ADD_MODELS:
                $rows[] = array('url' => asort_get_url(CAR_HOMEPAGE, $row['maker_url'], $row['model_url']), 'label' => $row['model_name'], 'image' => fa_model_image_path("thumb", $row['maker_url'],$row['model_url']));
                break;

            case TBL_BIKE_MODELS:
                $rows[] = array('url' => asort_get_url(BIKE_HOMEPAGE, $row['maker_url'], $row['model_url']), 'label' => $row['model_name'], 'image' => fa_bike_model_image_path("thumb", $row['maker_url'],$row['model_url']));
                break;

            case TBL_TRUCK_MODELS:
                $rows[] = array('url' => asort_get_url(TRUCK_HOMEPAGE, $row['maker_url'], $row['model_url']), 'label' => $row['model_name'], 'image' => fa_truck_model_image_path("thumb", $row['maker_url'],$row['model_url']));
                break;

            case TBL_BUS_MODELS:
                $rows[] = array('url' => asort_get_url(BUS_HOMEPAGE, $row['maker_url'], $row['model_url']), 'label' => $row['model_name'], 'image' => fa_bus_model_image_path("thumb", $row['maker_url'],$row['model_url']));
                break;

            default:
                // nothing sensible to do here
                break;
        }
    }

$sql = "SELECT model_name, maker_url, model_url, tbl_name FROM ITEM_MODELS  WHERE model_status = '1' AND model_url != '${model_url}' AND model_name LIKE '%${q}%' LIMIT 3)";
$sort_keys = [
    TBL_CAR_ADD_MODELS => CAR_HOMEPAGE,
    TBL_BIKE_MODELS => BIKE_HOMEPAGE,
    TBL_TRUCK_MODELS => TRUCK_HOMEPAGE,
    TBL_BUS_MODELS => BUS_HOMEPAGE
];
    while($row = mysql_fetch_array($res))
    {   
        $rows[] = array('url' => asort_get_url($sort_keys[$row['tbl_name']], $row['maker_url'], $row['model_url']), 'label' => $row['model_name'], 'image' => model_image_path($row['tbl_name'], "thumb", $row['maker_url'],$row['model_url']));
    }

这将大大简化您的PHP代码，如下所示：

$sql = "SELECT model_name, maker_url, model_url, tbl_name FROM ITEM_MODELS  WHERE model_status = '1' AND model_url != '${model_url}' AND model_name LIKE '%${q}%' LIMIT 3)";
    while($row = mysql_fetch_array($res))
    {   
        switch($row['tbl_name']) {
            case TBL_CAR_ADD_MODELS:
                $rows[] = array('url' => asort_get_url(CAR_HOMEPAGE, $row['maker_url'], $row['model_url']), 'label' => $row['model_name'], 'image' => fa_model_image_path("thumb", $row['maker_url'],$row['model_url']));

        }
    }

    }

然后，我们可以通过切换用于数组查找的case语句来继续简化代码，并为

*\u image\u path

函数创建一个包装器，该包装器基于相同的

$row['tbl\u name']

值调用正确的

fa\u FOO\u model\u image\u path

，也许最终会让我们得到如下结果：

除了@Trent的建议外，您还可以将常量作为字符串直接放入：

“（选择model\u name、maker\u url、model\u url，”。.TBL\u CAR\u ADD\u MODELS“”作为TBL\u name FROM.TBL\u CAR\u ADD\u MODELS。”。

@TML它不会将表名作为列名返回

“…”。.TBL\u CAR\u ADD\u MODELS.”。。。“

应该为您提供常量TBL\u CAR\u ADD\u MODELS的值，用单引号括起来；在其后添加“as TBL\u name”将导致数据库返回一个名为“TBL\u name”的伪列，该值是插入的字符串常量（正确引用）输入字符串。如果您正在努力解决此问题，可能会更新问题，以便我们可以看到您迄今为止的尝试。除了@Trent的建议，您还可以将常量作为字符串输入：

$sort\u key=（汽车主页|自行车主页|卡车主页|公共汽车主页）；

，并为

*\u image\u path

函数创建一个类似的包装器，该包装器基于相同的

$sort\u key

值调用正确的

fa\u FOO\u model\u image\u path

。然后，我们可以通过切换那些case语句来设置一个变量，例如

$sort\u key=（CAR|u HOMEPAGE | BIKE|u HOMEPAGE | TRUCK|u HOMEPAGE | BUS|u HOMEPAGE）

，并为

*(图像)路径

函数创建类似的包装器，该函数基于相同的

$sort(排序)键

值调用正确的

fa u FOO(模型)图像(路径

）。
